As a leading manufacturer with over 25 years of expertise, Anping County Boli Hardware Wiremesh Products Factory (established 1998) proudly presents our premium Galvanized Round-Perforated Dewatering Screen with 2mm Aperture, 1.5mm Thickness, and 500mm Diameter. This screen is engineered to deliver exceptional dewatering performance in demanding industrial environments, combining precision perforation with robust galvanized construction. Our factory's annual export value of US$5-10 million and extensive global reach (covering North America, Europe, Asia, Africa, and Oceania) attest to the reliability and quality that customers worldwide trust.
This dewatering screen is specifically designed for efficient solid-liquid separation in mining, wastewater treatment, food processing, and chemical industries. The 2mm round apertures ensure consistent particle retention, while the 1.5mm thickness provides structural integrity without compromising flow rates. The 500mm diameter makes it ideal for use in vibrating screens, trommel screens, or standalone dewatering units. Each screen is manufactured under strict quality control to guarantee dimensional accuracy and long service life.
Below we detail the key features, technical specifications, and advantages that make this product a preferred choice for professionals.
Key Features & Benefits
- Precision Perforation: Each hole is accurately punched to 2.0mm ±0.1mm, ensuring uniform dewatering performance and consistent particle size classification.
- Superior Corrosion Resistance: Hot-dip galvanized coating (zinc layer thickness ≥85μm) provides excellent protection against rust and chemical attack, extending service life in wet or acidic environments.
- High Open Area Ratio: The round hole pattern achieves up to 40–50% open area, maximizing water throughput while retaining solids effectively.
- Durable Construction: Made from high-quality galvanized steel sheet with 1.5mm thickness, the screen withstands heavy loads, vibration, and impact without deformation.
- Easy Installation: Standard 500mm diameter fits most existing equipment frames; custom sizes available upon request for retrofitting or new projects.
- Low Maintenance: Smooth surface and anti-clogging hole design reduce cleaning frequency and downtime.
- Versatile Applications: Suitable for sand and gravel dewatering, coal slurry processing, mineral beneficiation, agricultural drainage, and industrial filtration.

Why Choose Our Galvanized Dewatering Screen?
Our factory has been producing perforated metal screens since 1998, and we understand the critical role of dewatering in industrial processes. Unlike standard screens, our product features a staggered hole pattern that maximizes open area while maintaining structural strength. The 2mm aperture is carefully selected to balance fine particle retention and high flow rate, making it suitable for applications such as:
- Mining & Quarrying: Dewatering of sand, gravel, and crushed stone aggregates.
- Wastewater Treatment: Solid-liquid separation in sludge dewatering and industrial effluents.
- Food Processing: Draining liquids from fruits, vegetables, and grains.
- Chemical & Pharmaceutical: Filtering and drying of powders and granules.
- Agriculture: Separating solids from animal waste or irrigation water.
The galvanized coating ensures that the screen remains rust-free even when exposed to moisture, salts, and mild chemicals. Each screen is individually inspected for hole uniformity, flatness, and edge finish before packing. Our production capacity allows us to fulfill large orders (up to 10,000 pieces per month) while maintaining consistent quality.
Client Benefits at a Glance
- Reduced Downtime: The smooth surface and anti-clogging design minimize blockages, keeping your operation running efficiently.
- Longer Service Life: Hot-dip galvanizing provides 5–10 times better corrosion resistance than painted or untreated screens.
- Cost-Effective: Competitive pricing without compromising quality, thanks to our direct factory manufacturing.
- Customization: We can adjust aperture size, thickness, diameter, and material (e.g., stainless steel upon request) to match your specific needs.
- Fast Shipping: With multiple ports (Tianjin, Qingdao, Shanghai, Foshan), we ensure timely delivery worldwide.
Frequently Asked Questions (FAQ)
-
Q: What is the tolerance on the aperture size?
A: Our standard manufacturing tolerance is ±0.1mm for 2mm apertures. For tighter tolerances, please contact us with your requirements. -
Q: Can I use this screen for high-temperature applications?
A: The standard galvanized screen is suitable for temperatures up to 80°C. For higher temperatures (e.g., 200°C+), we recommend stainless steel screens, which we can produce upon request. -
Q: How do I clean the screen to prevent clogging?
A: The round holes and smooth surface make cleaning easy. Use a water jet, air blow, or gentle brushing. Avoid harsh chemicals that may damage the galvanized coating. -
Q: Is the screen suitable for vibrating or rotating equipment?
A: Yes, the 1.5mm thickness provides sufficient rigidity for most vibrating screens and trommel drums. For heavy-duty applications, we can increase thickness to 2.0mm or more. -
Q: What is the minimum order quantity (MOQ)?
A: For standard sizes, MOQ is 50 pieces. For custom sizes, please inquire — we can accommodate smaller quantities for sample testing. -
Q: Can you provide a sample before bulk order?
A: Yes, we offer sample orders. The sample cost is deductable from the final bulk order. Please contact our sales team for details. -
Q: How long does shipping take to North America?
A: Typically 15–25 days by sea from Tianjin or Qingdao ports. Express delivery (DHL, FedEx) is available for smaller quantities. -
Q: What packaging do you use?
A: Each screen is individually wrapped in protective film, then packed in sturdy wooden crates or pallets to prevent damage during transit.
